HERMAN MARTIN, OF ILION, NEW YORK.

GAS-HEATER.

SPECIFICATION forming part of Letters Patent No. 792,715, dated June 20,1905.

Application filed November 18, 1901. Serial No. 82,625-

To all whom it may concern:

Be it known that I, HERMAN W. MARTIN. a citizen of the United States,residing at Ilion, in the county of l-Ierkimer and State of New York,have invented certain new and useful Improvements in Gas-Heaters, ofwhich the following is a specification, reference being had therein tothe accompanying drawings.

My invention relates to a gas-heater; and it consists in the mechanismherein more fully described and claimed.

The purpose of my invention is to provide an improved method of heatingby gas and other fuel, which will be hereinafter more fully pointed outand claimed.

In the drawings, Figure 1 represents a front view of my heater, brokenlines indicating parts removed. Fig. 2 is a side elevation of -Fig. 1, asponge and sponge-holder being also shown in section-lines. Fig. 3 is aplan view Fig. 4 is a section taken in the plane of the line A B,Fig. 1. Fig. 5 is a top view of the gas-heater. Fig. 6 is a reversedview of Fig. 5.

Having described my invention in reference to the figures illustrated inthe drawings,

I will now proceed to describe the same in detail, in which similarnumerical references will refer to corresponding parts in the severalviews.

I preferably provide wall-bracket 1, provided at its top with opening 2for sustaining the same on the wall, which carries at its epposite endbracket or stand 3, which may or may not be provided with legs 4. Inthis instance I provide supporting'sbrackets 5 5, which are secured toback wall and bracket 1 for supporting thereon liquid-tank 6, which inthis instance is provided with tube 7, through which the liquid is freeto descend into a sealed heating-tank 8. For securing circulation andpreventing explosion I provide circulating-tube 9, which enters the wallof the tank at 10 and is connected at 11 with the sealed heating-tank atits edge or side. By this arrangement a continuous circulation ofliquids may be maintained through the fluid-tank and the sealedheating-tank, and

1 thereby prevent explosion which might occur heating-tank, which woulddrive the liquid up through pipe 7, and thereby produce an explosion.

The sealed heating-tank is supported below the liquid-tank 6 and abovestand 3 and is so arranged that the liquid will flow into the sealedheating-tank by gravity. Beneath the sealed heating-tankI provide agas-burner 1.2, which'I illustrate as consisting of the perforated metaldisk 13, which forms its upper surface. Beneath this disk 13 I provide asecond disk 14, which is also perforated and which is secured to theupper disk by a collar 15, connecting the two, which collarmaybe formedby turning up the edge of the disk. The gas is fed through tube 16 intothe space between the disks, where it passes through the perforation inthe upper disk and there is burned, the perforations in the lower diskbeing provided for the admission of air to mix with the gas. Tube 16 isprovided to supply the gas and is bent, as shown in Fig. 6, to form aseat or'base for the gas-burning portion of my de- Vice.

For admitting air into the gas I provide transverse tube 18, which isopen at both ends to admit the air and permit the same to be mixed withthe gas as it passes from the gassupply into the convoluted tube locatedunder the perforated burner 12, and by admitting air through perforatedbottom 13 under the perforated burner a sufficient supply of air ismixed with the gas to produce the requisite quantity of heat.

Gas-supply pipe 19 passes through the tube 18 and a flow of gas thereinis controlled by the stop-cock 20 (illustrated in Fig. 1) by permittingthe screw-threaded stop-cock to enter the wall of the gas-supply pipefor regulating the flow of the gas into the burner, the gas beingpermitted to pass through the end of the gas-pipe.

By locating burner 12 under sealed heatingtank 8, so that the heatgenerated by the burner is carried against the under side of the sealedheating-tank 8, the required degree of heat can be obtained at a nominalexpense.

The stand 3 is provided with an opening of a radially-slotted outline,as at 26, (shown in Fig. 4,) to permit the heated air to come into ICOcontact with the sealed heating-tank. I illustrate this opening in thegeneral form of radial fingers, which offer a radiating-surface.

For using the gas-burner for heating and other purposes I provide theusual heatingplate 21, (best illustrated in Fig. 4,) which may be eitherintegral with or independent of bracket or bottom 3.

For supplying the heated liquid to the surface which may be required tobe cleansed I provide outlet-pipe 22, which is controlled by stop-cock23, which is attached to receivingfiange 25, in which I insert sponge 27or other fibrous material, so that the heated liquid passesthroughopening 28 into the sponge or other fibrous substance, so thatwith a small quantity of heated liquid a warm sponge-bath may be taken.By the continuous flow of heated liquid through the sponge or otherfibrous substance, and at the same time that the sponge or other fibroussubstance may be replaced from time to time, in consequence of thisoperation the sponge or other fibrous substance is kept clean by thecontinuous outflow of the liquid through the same.

What I claim as new, and desire to secure by Letters Patent, is

In combination, an integral stand havinga standard and a base portion,said latter comprising a heating-plate formed with a centralheat-directing opening and with slots radiating from said centralopening, a burner beneath the heating-plate, supporting-arms fixed tothe standard, a liquid-tank resting upon said arms, a heating-chamber.in open communication with and supported solely by the tank immediatelyabove the heat-directing opening in the plate, and an outlet-tube fromthe heating-chamber.

In testimony whereof I affix my signature in presence of two witnesses.

HERMAN W. MARTIN.
